What Causes Picking Errors?

When a warehouse picker and loader makes an error, it can be very costly. For one thing, when the driver checks his truck and there is an error on loading, he has to come back into the warehouse and get it corrected, which makes him late to his accounts and can put a strain on time stops, etc. If he doesn't catch the error, he has to cut orders and change invoices and then check-in takes longer. It's a mess.In
